DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described with reference to the accompanying figures, wherein the numbered elements in the following written description correspond to like-numbered elements in the figures. A portable swing seat 20 in accordance with the present invention is illustrated in FIGS. 1 and 2 to include a flexible seat portion 22, a support assembly 24, a spreader 26, and an attachment assembly 28 having an attachment member or strap 30. The attachment strap 30 may be disposed about an object, such as tree 32, and is connected to the support assembly 24 whereby an individual 34 may recline in a seated position on seat portion 22 and be supported by swing seat 20. The support assembly 24 includes a pair of support arms or straps 36 a, 36 b that are connected to the seat portion 22 at one end, with the spreader 26 extending between the support straps 36 a, 36 b above the seat portion 22. The spreader 26 thus maintains spacing between the support straps 36 a, 36 b such that support straps 36 a, 36 b do not angle upwardly to the connection point 38 with attachment strap 30, which may undesirably result in the straps 36 a, 36 b contacting individual 34, such as about the shoulders, and/or restrict movement within swing seat 20.

Referring now to FIGS. 1-5, in addition to support straps 36 a, 36 b, the illustrated support assembly further includes a hanging member or strap 40 that is connected to attachment strap 30 at connection point 38. Support assembly 24 further includes a pair of pockets or receptacles 42 a, 42 b for receiving the ends 44 a, 44 b of spreader 26.

Each support strap 36 a, 36 b includes an upper strap 46 and a lower strap 48, with the upper strap 46 and lower strap 48 being connected together by a strap adjuster 50. A lower end 52 of lower strap 48 is affixed to seat portion 22, such as by being sewn or stitched together, and the upper end 54 of lower strap 48 is looped about a portion of strap adjuster 50 and affixed back upon itself, such as by being sewn together in similar fashion as that shown in FIG. 6. An upper end 56 of upper strap 46 is affixed together with one of pockets 42 a, 42 b by being sewn or stitched 58 together as shown in FIGS. 4-5, with dashed lines being used to indicate stitching throughout the various drawings. The lower end 60 of upper strap 46 is looped through strap adjuster 50 whereby each support strap 36 a, 36 b may be lengthened or shortened. The adjustability of support straps 36 a, 36 b in this manner enables swing seat 20 to be conveniently adjusted to accommodate differences in user preference and/or height, as well as provide flexibility based on the location, shape and/or orientation of objects, such as tree trunks, limbs, or rocks, to which swing seat 20 may be connected. As shown, strap adjuster 50 is a conventional metal buckle, such as may be supplied by Granat Industries of Elk Grove Village, Illinois, having a spring loaded member with gripping teeth that are biased into engagement with the strap material for retaining the strap in place. Alternative strap adjusters, however, may be employed within the scope of the present invention.

Hanging strap 40 extends between pockets 42 a, 42 b and upper ends 56 of upper straps 46 and is connected to attachment member 30. As understood from FIGS. 3-5, each end 62 a, 62 b of hanging strap 40 is affixed by stitching 64 to a respective support strap 36 a, 36 b within, as well as to, a respective pocket 42 a, 42 b. As understood from FIG. 6, an end 66 of attachment member 30 is turned back upon itself and sewn or stitched 68 together to form a loop 70 through which hanging strap 40 is passed, with the mid-point of hanging strap 40 being affixed to attachment member 30 by being stitched 72 within loop 70.

In the illustrated embodiment, the material of support straps 36, hanging strap 40, as well as attachment member 30, is a 3/4 inch nylon strap. However, alternative straps and/or sizes may be employed within the scope of the present invention. Alternative types of materials may also be employed and the term “strap” should be understood to include alternative flexible members that are able to support loads in tension, such as ropes, cords, lines, or otherwise.

Referring again to FIGS. 2-5, each pocket 42 a, 42 b is formed by doubling a material back over upon itself, such as a 2 inch wide nylon strap, and stitching 74 along the edges 76 to leave an opening 78 for receiving a respective end 44 a, 44 b of spreader 26. Still further, the stitching together of pocket 42, support strap 36 and hanging strap 40 creates a strong interconnection simultaneous with the formation of pocket 42.

The spreader 26 shown in FIGS. 2 and 3 is collapsible, as understood from FIGS. 9 and 10, and is constructed from three spreader members 82 (FIG. 1) that, in the illustrated embodiment, comprise hollow end tubes 84 a, 84 b and a hollow center tube 84 c (FIG. 2), each of which is constructed of steel and is approximately 11.5 inches long. Each end tube 84 a, 84 b may be connected to center tube 84 c with center tube 84 c having a slightly greater diameter whereby end tubes 84 a, 84 b may be inserted into internal cavities 86 of center tube 84 c. As shown in FIG. 3, center tube 84 c includes internal cavity 86 into which end tube 84 a is inserted, with a similar internal cavity being located at the opposite end of center tube 84 c for receiving end tube 84 b. An elastic member 88, such as a bungee cord, is centrally disposed through hollow end tubes 84 a, 84 b and center tube 84 c (FIG. 3). As understood from FIG. 3, each end 90 of elastic cord 88 is affixed within one of the pockets 42 a, 42 b, such as by stitching ends 90 within pocket 42 via the stitching affixing pocket 42, support strap 36, and hanging strap 40 together. Elastic member 88 thereby provides a biasing force aiding in retaining tubes 84 together when interconnected, with the affixing of ends 90 of elastic member 88 to pockets 42 aiding in assembly of swing seat 20, as the spreader 26 will be maintained in proper position. An alternative spreader, however, may be constructed with more or less than three spreader members, may not be collapsible, and/or may not include an internal elastic member, or may include an elastic member that is not affixed to pockets.

As noted, attachment strap 30 is used to support swing seat 20, such as around the trunk of tree 32 as shown. Attachment assembly 28 includes a connecting link 94 used to enable attachment strap 30 to form a loop 96 for connecting to an object. Connecting link 94 includes a strap adjuster 98 connected to a ring 100 by a length of strap 101, with strap 101 being connected to strap adjuster 98 and ring 100 by stitching the strap 101 back over upon itself in like manner to that described above. Connecting link 94 further includes a hook member 102, which in the illustrated embodiment comprises a conventional carabiner 104, with ring 100 being linked to carabiner 104. In use, attachment strap 30 is positioned within carabiner 104 as shown in FIG. 2. Although a ring may be utilized in place of carabiner 104 as a hook member, carabiner 104 includes a pivoting arm or gate 106, which aids in the looping of attachment strap 30 around an object by allowing attachment strap 30 to be inserted into carabiner 104 via gate 106 rather than having to thread attachment strap 30 through a central opening. To install swing seat 20, attachment strap 30 is initially wrapped around tree 32 when disconnected from carabiner 104. Upon encircling tree 32, carabiner 104 is connected to attachment strap 30 by passing attachment strap 30 through the gate 106 of carabiner 104 such that attachment strap 30 is contained within carabiner 104 as shown in FIG. 2. The length of attachment strap 30 extending out of strap adjuster 98 may then be pulled to cinch attachment strap 30 to tree 32. Swing seat 20 is shown affixed to the trunk of tree 32 in FIG. 1, with the trunk also thereby acting as a backrest for an individual 34 using swing seat 20. Swing seat 20 may alternatively be connected to a branch of tree 32 or other supporting objects.

The connection of support straps 36 a, 36 b to seat portion 22 may be understood with reference to FIGS. 2, 7 and 8. Flexible seat portion 22 may be constructed of a CORDURA® material, canvas, or other such material and is generally rectangular in shape in the illustrated embodiment, with the lower ends 52 of lower straps 48 being connected to opposite ends 108 of seat portion 22. The lengthwise edges 110 of seat portion 22 are folded over and stitched 112 such that seat portion 22 in the illustrated embodiment has a width 114 of approximately 8.5 inches. As understood from FIGS. 7 and 8, for added strength, lower ends 52 may be sewn or stitched to the underside 116 of scat portion 22 together with a pair of flaps 118 a, 118 b. Lower end 52 is initially passed through an aperture 120 in seat portion 22 and the corner end portions of seat portion 22 are folded over to form flaps 118 a, 118 b (see arrow identifiers A and B in FIG. 7), with the flaps 118 a, 118 b being stitched 22 to lower end 52 along the length of lower strap 48. The flaps 118 a, 118 b are then again folded over together and stitched 124 to the underside of seat portion 22 (see arrow identifier C in FIG. 7). In the illustrated embodiment seat portion is approximately 32 inches long.

As understood from FIGS. 9 and 10, swing seat may be readily collapsed for compact and convenient storage and carrying when not in use, such as within a pocket of an individual. As shown, the various spreader members of spreader assembly may be collapsed and folded over one another, with the support assembly being wrapped there about. The spreader and support assembly may then be rolled up within seat portion with the attachment strap used to wrap around seat portion to retain swing seat in the collapsed orientation of FIG. 10. The width of seat portion is approximately equivalent to the length of the collapsed spreader assembly as a result of the size of each spreader member, with seat portion being slightly smaller in width relative to the length of each spreader member in the illustrated embodiment, whereby the collapsed swing seat remains compact with the overall size minimized and without components of the spreader assembly excessively extending out of the rolled up seat portion. Still further, swing seat may be used as a sling to haul or pull items, such as by a hunter using swing seat to pull a deer felled in the woods to an area accessible by a vehicle. For example, the seat support may be placed across the chest of the user, with one support strap extending over the top of one shoulder and the other support strap extending under the shoulder of the opposite arm, with the attachment strap being tied to the object to be pulled.

Although discussed in above in accordance with the illustrated embodiment, various alternatives may be employed. For example, alternative methods of connecting the various straps and seat portion together may be utilized in place of stitching, such as riveting or the like. The support assembly may alternatively be constructed of a unitary strap, including either with or without adjustable length side portions. Still further, a swing seat may be constructed having a unitary spreader and/or a spreader that is not straight or not hollow.

Swing seats in accordance with the present invention provide a convenient and portable seating apparatus for use in settings such as the outdoors. The adjustable length support straps enable swing seat to be modified to the preferences of the user, including based on the user's height as well as the object to which the seat is affixed, with the spreader maintaining the spacing of the support straps to inhibit support straps from undesirably contacting the user and/or restricting the user's movement within swing seat. Swing seat may be readily collapsed for transport, including by way of a multi-part collapsible spreader assembly enabling swing seat to be compactly rolled up for carrying.
